Abstract CONSISTING OF (A) A METAL COMPOSITION COMPRISING VANADIUM, MOLYBDENUM, TUNGSTEN, COBALT, TANTALUM OR NIOBIUM MATERIALS OR MIXTURES THEREOF OR (B) MIXTURES OF MATERIALS COMPRISING CANADIUM, MOLYDBENUM, TUNGSTEN, COBALT, TANTALUM OR NIOBIUM MATERIALS OR MIXTURES THEREOF WITH A NICKEL, IRON OR CHROMIUM MATERIAL OR MIXTURES THEREOF, THE WEIGHT RATIO OF SAID HYDROGENATION-DEHYDROGENATION COMPONENT TO SAID ALKALI METAL COMPOUND, EACH CALCULATED ON THE BASIS OF THE OXIDES THEREOF, BEING LESS THAN 5:1. 1. A PROCESS FOR THE PREPARATION OF HYDROGEN AND CARBON DIOXIDE WHICH COMPRISES INTRODUCING A GAS MIXTURE CONTAINING MONOXIDE AND STREAM AT A TEMPERATURE VARYING FROM ABOUT 300* TO 700* F. INTO A FIRST SHIFT-REACTION STAGE AND CONTACTING SAID GAS MIXTURE THEREIN WITH A CATALYST TO FROM A REACTION MIXTURE, COOLING AT LEAST A PORTION OF SAID REACTION MIXTURE FROM SAID FIRST STAGE TO A TEMPERATURE OF ABOUT 300* TO ABOUT 700*F. AND INTRODUCING AT LEAST A PORTION OF SAID COOLED REACTION MIXTURE TO AT LEAST ONE ADDITIONAL SHIFT REACTION STAGE CONTACTING THE SAME THEREIN WITH A CATALYST, THE TEMPERATURE WITHIN EACH SAID REACTION STAGE BEING MAINTAINED ABOVE THE DEW POINT TEMPERATURE OF THE REACTION MIXTURE AND THE PRESSURE WITHIN EACH SAID REACTION STAGE BEING MAINTEINED BELOW THE DEW POINT PRESSURE OF SAID REACTION MIXTURE AND RANGING FROM ABOUT ATMOSPHERIC TO ABOUT 3,000 P.S.I.G., THE CATALYST IN EACH REACTION STAGE COMPRISING (I) AN ALKALI METAL COMPOUND DERIVED FROM AN ACID HAVING AN IONIZATION CONSTANT OF LESS THAN ABOUT 1X10-3 AND (II) A HYDROGENATION-DEHYDROGENATION COMPONENT SELECTED FROM THE GROUP
